The ultrastructural changes occurring during defined stages of the transition of dormant Bacillus cereus T spores into heat-sensitive forms were investigated. The coat of the heat-activated spores displayed conspicuous striations across its middle layer. Electron microscopy of thin sections of heat-activated spores revealed the presence in the spore of a layer consisting of hexagonally oriented subunits. It was demonstrated that the subcoat region, but not the cortex, disappears rapidly during germination of B. cereus T spores. The fibrous structures apparently associated with the spore coat remain virtually unchanged during the entire course of activation and germination.
研究了蜡样芽孢杆菌T型休眠孢子转变为热敏形式的特定阶段所发生的超微结构变化。热激活孢子的外壳在其中层呈现出明显的条纹。热激活孢子薄片的电子显微镜检查显示，孢子中存在一层由六边形排列的亚基组成的结构。结果表明，蜡样芽孢杆菌T型孢子萌发过程中，孢子外衣区域而非皮层迅速消失。在整个激活和萌发过程中，明显与孢子外壳相关的纤维结构几乎保持不变。
